Once you climb past the rats and turn the upper red control wheel, the flies leave Ratman and attack you. You will have to elude them by rapidly running right, then left, to climb the large pipes at the center. From there you can leap left to where Ratman is, and handcuff him.

The flies stay around Ratman in the control room, and there is no way past them. However, you can get them to leave him: jump past the three rats at the upper right and turn the red control wheel. This dumps sludge on Ratman and chases the flies, but they attack you. Get away from them and jump to the large center pipe, from which you can jump over to Ratman and cuff him.
Once you have dumped sludge on Ratman, his rats run away. But the stinging flies will attack you. Avoid them long enough to jump to the large pipe at the center, then over to Ratman. Cuff him.
In the sewers on Super Power Island, Ratman is guarded by rats and stinging flies. When you find him, go right and jump the rats to reach the final red wheel at upper right. This dumps sludge on Ratman and the flies. Now they will chase and sting you. Go far right, then run back left and quickly climb the BIG pipe in the middle, from which you can jump to Ratman. The flies are always right behind you.
You have to go around them. In the control room, the ones at upper right are moving back and forth in a regular pattern.

(see related question)
You have to get the flies away from Ratman to defeat him. Climb up past the three rats on the right side to reach the final red wheel. Click it to dump sludge on Ratman. Now the flies attack you, but you can dodge them long enough to jump to the large center pipe, and over to where Ratman is.
You can't. You have to go around them. They move in regular patterns and you can jump past them in a couple of different ways, to reach the red control wheel at the upper right. When you do, the flies will leave Ratman and attack you, so dodge them and climb the big pipe at the center to jump over to Ratman.
The swarm of little black objects around Ratman are stinging flies (not bees). They only attack you at first when you try to capture him. When you reach and turn the red wheel at the upper left, sludge is dumped on them and on Ratman. They will then proceed to attack you. You have to temporarily avoid them, then jump up on the big center pipe and over to Ratman, where you knock him out and cuff him.
